Chapter 159: Relationship change

　　 In supplementary experiments, SEM and GIWAXS are relatively troublesome.
　　 The former is a scanning electron microscope, which is used to characterize the film thickness of the effective layer of the device under the best performance.
　　On the one hand, it is not possible to test directly in the laboratory, it needs to be tested in the department.
　　 On the other hand, the devices of these four systems are still in the process of performance optimization, and this experiment cannot be carried out.
　　 Otherwise, suppose the current optimal conditions are "to the receptor mass ratio 1:1, total concentration 16 mg/ml, chlorobenzene solvent, 110 degrees Celsius, true thermal annealing, 3000r.p.m., no other post-processing methods...".
　　The film thickness was measured to be 105 nm.
　　 After waiting a few days, the experimental conditions were optimized again, and the device performance improved again.
　　 There is a high probability that the film thickness will change, so you have to test it again under the new conditions.
　　GIWAXS, go to the magic light source to test.
　　 There is one last test opportunity this year, which is scheduled for next Saturday.
　　 This test is an evening file, that is, from nine o'clock in the evening to nine o'clock the next morning, and all night.

　　Han Jiaying has activities of the Boiling Point Club this week, with rehearsal on Tuesday and a formal performance on Wednesday, so she took two days off.
　　 On Tuesday afternoon, she sent five tickets to the lab friends, and then left in a hurry.
　　 The current main members of the laboratory, compared with the previous ones, are equivalent to adding only one new school girl.
　　 As for Cheng Mingbo, I met twice in the first week, and then once a week later, and only once in almost two weeks now.
　　Because he is not in Xu Qiu's control, Xu Qiu still doesn't know what is going on with him now.
　　 Is it simply because of heavy schoolwork that I can’t spare time?
　　 still choose to run away for other reasons;
　　 or found another research group, stepped on N boats.
　　 Whatever the reason, apart from Wu Feifei's occasional envious look at Xu Qiutou, the existence of Cheng Mingbo has little effect on others.
　　 "Foot on N boats" also reminded Xu Qiu of one of his talented classmates, Fang Xiaotong, to be precise, he ranked first in talented achievements.
　　 The relationship between Xu Qiu and her is roughly between a nodding acquaintance and an acquaintance. They belong to the same kind of academic masters and occasionally overlap, but there are not many personal relationships.
　　 Fang Xiaotong joined the research group since his sophomore year, and has changed four groups at the frequency of about one research group every semester.
　　 She has been to several major groups in the Department of Materials.
　　 In the end, she chose to join a research group of an academician of the Department of Chemistry, and she also went to the Department of Chemistry as an inter-professional undergraduate insurance program.
　　 Maybe I think the temple of the material department is too small to use her talents.
　　 After all, there is no academician in the department of materials.
　　 Equipment Academy and Jiang Wan Xiancai each have an academician.
　　 But those units are listed separately. Although they recruit students together with the Department of Materials, they are not managed by the Department of Materials and have their own factions.
　　 I have to say that there are still two brushes that can be listed.
　　 Like Zhan Yuntao, the big boss of the Equipment Institute, he has a very high level of scientific research and countless proficiency students. The research direction is the direction of bacteria engineering equipment, and there is no shortage of project funds.
　　 In addition, policy benefits will also be tilted towards their research group.
　　 For example, a separate national award quota is allocated each year.
　　 Another example is that in other laboratories, students and teachers manage the experimental equipment themselves and handle the trivial matters such as reimbursement.
　　 Zhan Yuntao’s research team hired two administrative staff separately, one was responsible for the registration and management of the laboratory’s instruments, laboratory cleaning, and the other was responsible for project funding management and financial reimbursement.
　　Of course, these administrative staff are not staffed and their income is average, but they are pretty idle.
　　 These things were also learned by Xu Qiu when he entered the research group and chatted with the seniors and sisters.
　　 Before entering this line, these things are difficult to inquire.
　　 Regarding scientific research, a lot of things laymen see are the tip of the iceberg. Only when you really get started will you discover how big the world is under the iceberg.
　　 Speaking of which, in addition to Fang Xiaotong this year, he also chose to stay in school for the first place in grade point.
　　 As for the electrical engineering major, Xu Qiu is not very familiar with it and is not clear about the specific situation.
　　The one with the highest score in materials and materials chose Yuan Shu's research group who went to Jiangwan Xiancai.
　　 Yuan Shu is mainly related to electron microscopy. Although he is not an academician, he is also an industry leader. He has focused on the field of electron microscopy for more than 20 years and is proficient in all kinds of electron microscopy. There are tens of millions of electronic microscopy equipment in the laboratory.

When 　　 school girl was away, Xu Qiu had to do the experiment by himself.
　　 He planned a little bit and decided to perform the three characterizations of UV-vis, PL, and CV first.
　　 Although there are three tests, there is no need to prepare the device, just spin coating to prepare the thin film, which does not consume too much time.
　　 With drawing and simple analysis of data, it should be done in two days.
　　 When the school girl will return, she can use the name "help her deepen and strengthen her experimental ability" to help with the experiment.
　　 Just as Xu Qiu got up to go to the laboratory, Chen Wanqing called him:
　　 "Brother, you want to measure the spectrum, right? Help me measure two samples too, okay?"
　　 "What sample?" Xu Qiu asked.
　　 "For my three systems, the ratio of the receptors was changed later, so the earlier test cannot be used, and the spectrum must be tested again." Chen Wanqing said.
　　 These three samples are obviously good for cutting, Xu Qiu secretly complained.
　　Of course, helping is sure to help, after all, it’s a senior sister, and I also used a begging tone~EbookFREE.me~Okay, where is the solution? "
　　 "In the glove box, I inserted the three sets of solutions into the glass bottle holders, with the date marked on them, the batch in December is."
　　 "What about the spin coating conditions?"
　　"Spray, 2500r.p.m., thermal annealing at 120 degrees Celsius for 10 minutes."
　　 "Okay, I wrote it down."
　　 After communicating with the senior sister, Xu Qiu suddenly discovered that the relationship between them, to be precise, was "the relationship between them as she thought," which changed over time.
When 　　 first joined the research group, the senior sister was his enlightenment mentor.
　　 As a tutor, she arranged experimental tasks for him, and both parties would feel reasonable.
　　 But later, his scientific research ability improved rapidly, even surpassing the senior sister. In her mind, the relationship between the two had changed and became equal.
　　 Even if Xu Qiu still recognizes her as a mentor in his heart, and believes that this relationship has not changed, Chen Wanqing no longer thinks like it did at the beginning.
　　 For example, now, to help her carry out an experiment, she has to change a softer tone.
　　 Actually, this is not necessary.
　　 This is also his philosophy. The relationship between master and apprentice is mainly maintained by emotion.
　　 If you rely on interests to maintain, you must always stay ahead of the curve, or you have to keep a hand at the key points.
　　 Not everyone can do the former, and the apprentice of the latter will definitely scold his mother behind his back.
　　 Xu Qiu believes that treating people with sincerity will at least not face the worst results.
　　 Just like him and Han Jiaying, although he said "investment" and "experimental tool man".
　　 But when thinking about problems, he still stands in the perspective of improving the experimental ability of the school girl, rather than just focusing on himself.
